Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehab center who understand how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehabilitation facility which has experience in handling this type of detoxification, and where the person can receive additional rehabilitation services to deal with all addiction issues.
